AUXILIARY MIXER FOR Specification of Letters Patent.

INTERNAL-COMBUSTION ENGINES.

Patented Nov. 3, 1914.

Application filed April 30, 1912. Serial No. 694,224.

To all whom it may concern Be it known that I, ROBERT D. LoosE, a citizen of the United States, and a resident of Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Auxiliary Mixers for Internal-Combustion Engines; and I do hereby declare that the following description of my said invention, taken in connection with theaccompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to improvements in auxiliary mixers for internal combustion or explosive motors, and it consists, essentially, in the novel and peculiar combination of parts and details of construction as hereinafter first fully set forth and described, and then pointed out in the claims.

In the drawings, to which reference has already been made, Figure 1 is a perspective viewof my invention and Fig. 2 a plan thereof. Fig. 3 is a similar view of a flat blank employed in my invention, and Fig. 4. an edge view of the same. Fig. 5 is a vertical section of my invention as installed in a manifold of a hydrocarbon motofi Like characters or symbols of reference are employed to designate similar parts in all the figures of the drawing.

It is a well known fact that while carbureters now used in motors of this class perform their functions of rolatilizing the hydrocarbon in a more or less perfect manner under proper conditions, yet, under widely variant circumstances, there is room for vast improyeinent in this respect. A carbureter functioning perfectly under normal conditions, under unusually applied loads upon the motor, or a sudden acceleration of speed of the same, or under adverse atmospheric conditions, will permit charges, in which the constituent elements of mixture have not been thoroughly commingled or united, to pass into the intake pipe leading to the motor cylinders, with the resultant misfires or flooding the cylinders Wltha-UIIVOldtilized hydrocarbons.

The essence of my inieution, therefore, resides in the provision of means for thoroughly inter-mingling, commingling, and

uniting the. eleinei-its of the explosive mixture after it leaves the carburetor and before it enters the cylinders of the motor. I accomplish this result by first cutting, dividing, or separating, as it were the charge as it leaves the carbureter, into a plurality of distinct and separate entities. To these I impart a \ortical or whirling motion in my mixer, and then permit them to recombine after passing therethrough. This whirling motion, once established, will continue in the flow of the mixture and results in a more intimate union, and a more thorough inter-mingling, of the constituent elements tlua'cof, than is otherwise possible. Moreover, the particles of liquid hydrocarbon carried through the carbureter in suspension are separated by this continuous whirling action, and their union with the oxygen accelerated.

Other objects of my invention are the production of mixers which can be applied to existing motors without disarranging any of the present parts or mechanism, and capable of being attached by the merest tyro; and, which can be cheaply and efticiently manufactured.

In Figs. 1,2, and 3 I illustrate how my mixer A is formed from a flat, metallic strip B. The vanes 6 are pierced out from and bent up at right angles to the plane of the strip B, and the flange C is notched along its edges and bent back. The strip B is then passed through a special pair of rolls, made for the purpose, and shaped into cylindrical form, with the vanes 6 projecting inwardly from the interior and the flange C exteriorly from the exterior thereof. This completes the mixer, which is adapted to be introduced directly into the intake pipe F of a motor, its flange C being clamped between the flange F of said intake and a flange C of a carbureter Gr, all as clearly illustrated in Fig. 5. It will thus be seen that my mixer can be attached to any existing motor by simply separating the intake and carbureter flanges, slipping my mixer into the intake,

in said flanges together.

In cases where the interior of the intake pipe has irregularities or inequalities in the casting, which would otherwise prevent the insertion of the mixer A therein, the same may be slightly squeezed together to pass the. obstruction, and when beyond the same,

the natural spring in the mixer will tend and then rebolt-- to spread the same apart and cause it to closely adhere to the interior of the intake p filaving thus fully described my invention, I claim as new and desire to secure unto myself by Letters Patent of the United States:
